<title>DESCRIPTION</title>
<para>
<emphasis remap='I'>porttime</emphasis> contains a list of tty
devices, user names, and permitted login times.
</para>
<para>
Each entry consists of three colon separated fields. The first field
is a comma separated list of tty devices, or an asterisk to indicate
that all tty devices are matched by this entry. The second field is a
comma separated list of user names, or an asterisk to indicated that
all user names are matched by this entry. The third field is a comma
separated list of permitted access times.
</para>
<para>
Each access time entry consists of zero or more days of the week,
abbreviated <emphasis>Su</emphasis>, <emphasis>Mo</emphasis>,
<emphasis>Tu</emphasis>, <emphasis>We</emphasis>,
<emphasis>Th</emphasis>, <emphasis>Fr</emphasis>, and
<emphasis>Sa</emphasis>, followed by a pair of times separated by a
hyphen. The abbreviation <emphasis>Wk</emphasis> may be used to
represent Monday thru Friday, and <emphasis>Al</emphasis> may be used
to indicate every day. If no days are given, <emphasis>Al</emphasis>
is assumed.

The following entries allow access only to the users
<emphasis>root</emphasis> and <emphasis>oper</emphasis> on
